LUBRICATOR.

Application filed July 2 3, 1924,. Serial lNo. 727,824.

T0 all whom t may concern:

Be it known that I, W EARL SNYDER, a citizen of the United States of America, and a resident of Cincinnati, in the county of Hamilton and State of Ghio, have invented new and useful Improvements in a Lubricator, of which the following is a specification,

This invention relates to lubricators and particularly to the type known as condensation displacement sight feed lubricators which are used in connection, with steam locomotives.

These lubricators are used to supply a specified quantity of Oil, drop by dropl, within a given period of time, to various moving parts of a locomotive as is well understood by those conversant in the art. Different types of locomotives require that various of the feeds from the lubricator be controllable while otherk feeds vare uncon,- trolled. Thek controlled and uncontrolled feeds differing with the types of locomotives have heretofore required that the lubricators be practically made special for each type, thereby entailing much expense in designing, patterns and the like and also causing much delay in that the specification for the desired type must be had before manuf facture can be started.

An Object of my invention is to provide a lubricator which may be arranged to meet the requirements of practically any locomotive.

Another Object is to provide a device ofy 'this character in which the labor and expense of such accommodation is comparatively small.

Another object is to provide a device of this type which may be carried by the manufacturer or by the supply division of the railroad, in such condition that a given lubricator may, with a relatively small amount of labor and expense, be placed in condition for use upon any type of locomotive.

These and other objects are attained by the means described herein and disclosed in the accompanying drawings,` in which:

Fig. 1 is a vertical cross sectional view of a lubricator of my invention.

Fig. 2 is a cross sectional view on line 2W2 of Fig. 1.

Fig. 3 is a cross sectional view on line 3:-8 of Fig. 1. y

Fig. l is a cross sectional view on line 4 of Fig. 1.

Fig. 5 is a crosssectional view on line 5-.5 of Fig. 1.

The lubricato-r reservoir 6 comprises a substantially tubular casing 7 `which is horizontally disposed in relation to the locomotive and is provided with a suitable filling port 8 and an oil level gauge 9. Extending downwardly from the casing 7 and integral therewithis a web 10 in which are disposed transverse apertures 11 which communicate at their tops with conduits'12, the tubular walls 13 of which are integral with the casing 7 (see Fig. 3) and the web 10. A series of the conduits 12, determined by the maximum knfumberof feeds required in the `lubricator, extend through the reservoir 6` and each ofthe conduits is in individual coinmunication by a suitable separate channel lllwitha separate equalizer tube 15 which extends upwardly into the steam condenser 16. v Forexample as shownat the leftof Fig. 1 the conduit 12ZL communicates with a channel 14a and equalizer tube lwvhile at the extreme right, of Fig.' 1 conduit 12 communicates through channel 14: with equalizer tube 15. In a like manner conduit 12 communicates through channel lllb toa `separate equalizer tube 15 (see Figs. 1 and 3). An oil supply tube 17 extendsthrough the reservoir 6 and communicateswith the in terior thereof near the top of saidreservoir and extends downwardly throughv the web 10 where it communicates with an Oil supply chamber `18. Extending parallel .with the reservoir 6 and located at the base of the 10 into feed chambers 250 disposed in suitable bosses 25 provided thereon. By reference to Figs. 4 and 5 it will be apparent that portions of the bosses 25 form a dividing wall between the feed chambers 250 and each of the channels 19 and 20 so that when it is desired to have any of the feeds through the regulating valves 24 controllable by the valve 22 it will be necessary only to drill holes 2G through those portions of the' bosses 25 which are common to the selected feed chambers 250 and the channel 20. This is accomplished as shown in Fig. 4 by providing the outer wall 27 of the web 10 with threaded bores 28, closable with plugs 29. Thus, as shown in Fig. 4 when it is desired to have the two outermost regulator valves controlled by the valve 22 it will require only the removal of the plugs 29 which will leave the walls of the feed chambers 250 all accessible to drill the holes 26. Should it subsequently be desired to change a given feed from a controllable one to a non-controllable one, the result is attainable by securing a threaded plug in the hole 26 thereby shutting off communica-tion between the desired feed regulator valve and the channel 20. In the same manner as will be apparent from Fig. 5 the uncontrolled feeds may be had by providing the threaded bores 28 and plugs 29 in the outer wall 27 and either drilling or plugging the holes 26 to establish or shut off communication between the desired feed chambers 250 and the channel 19, as may be required. The feed regulator valves 24 may be of any approved construetion as may also be the bulls eye sight glasses 280, these details not forming the invention set forth in this application. From the foregoing it will be apparent that the channels 19 and 2O extending parallel to one another across the entire web 10 will receive oil from the supply chamber 18. The channel 2O is controllable by the single control valve 22 so that a fiow of oil from the supply chamber 18 to the channel 20 may be readily established or shut o. The channel 19 which communicates with the ksupply chamber 18 through the port 23 is without a valve and therefore is in constant and uncontrolled communication `with the supply chamber 18. As is disclosed in Figs. 2, 3, 4 and 15, each feed chamber 250 has a thin wall portion separating said chamber from the individual channels 19 and 20 and as shown in Figs. 4 and 5, the plugs 29 are provided in the outer walls of the channels 19 and 2O so that they may be removed and communication provided between either controlled channel 20 or non controlled channel 19 by drilling` one of the holes 26 either through the lower common wall portion of a given feed chamber as shown in Figs. 3 and 4 to provide controlled 'feed chambers or by drilling through the upper portion of feed chamber 250 in the walls of both channels 19 and 2O and to provide threaded perforations 26 in both upper and lower common wall portions of each feed chamber 250 and to insert a plug in one of the two perforations in each feed chamber wall so that there would be communication between a given feed chamber and one of the channels. In practice, however, a lubricator seldom requires a change of controlled and uncontrolled feeds and therefore in view of the simple operation required in the device of this invention to provide either controlled or uncontrolled feeds, the device is made as disclosed herein, leaving the simple operation of adapting it to the desired feeds until the device is required for a given locomotive and the location of controlled and uncontrolled feeds is determined. In view of the fact that heretofore it was necessary to make up a special pattern and to especially make each lubricator for a given combination of controlled and uncontrolled feeds, it will be readily apparent to those skilled in the art that lubricators constructed according to this invention will enable both manufacturer and user to effect an enormous saving in labor and in time. This is especially true for the reason that use of special patterns and requirement for special core work is entirely eliminated and that the devices may be manufactured and carried in stock which has heretofore been impracticable by reason of the special nature of the devices and the great expense attached to the making of lubricators of the many and different combinations of feeds.

The operation lof displacement lubricators of this type being well understood by those versed in the art, will not require explanation in this application. The structure and operation of the steam condensation device of the invention may be of any approved type, for example as shown in my Patent #1,539,522, dated hIay 2G, 1925. From the foregoing explanation and in view of the disclosure in the drawings, especially Figs. 4 and 5, it will be apparent that there has beeny provided a lubricator which is practically universal in its adaptability to the requirements of steam locomotives. It should be understood of course that the number of feed regulator valves may be varied within the scope of this invention. It should be further noted that the character of" labor lrequired in adapting a lubricator of my invention to any given requirements, would be well within the skill of an ordinary mechanic versed in the art, the actual operations being nothing more than drilling and tapping the holes 26 and 28 and supplying the plugs 29 and the plugging of the holes 26 with suitable threaded plugs.

Vhat I claim is: l. In a lubricator of the class described the combination of an oil reservoir, a web below the reservoir and having therein a series of feed chambers, an oil supply chamber and a pair of channels communicating with the oil supply chamber and extending adjacent each feed chamber whereby portions of the web provide common wall portions between each of the channels, an oil supply tube providing communication between the top of the reservoir and the oil supply chamber, a valve controlling communication between the oil supply chamber and one of the channels whereby a controllable channel is provided, and means comprising plugs in the walls of both channels, removable to provide access for perforating a common wall portion of a selected feed chamber and one of the channels, whereby controllable and non controllable feed chambers are provided. 2.
